HAL_QSPI_AutoPolling_* delay between command and response

Hi All,I'm using a STM32H7 MCU with a ISSI IS25LP256D serial flash chip. (32MB.)I wrote a driver using a simple microcontroller and was able to read the Status Register by adding a 8uSec pause after the 0x05 command and the clock pulses to get the r...

Resolved! I've got a very strange situation on my STM32G0B0VE GPIO pin A8 gets to be the inverted signal of what PA9 is (it doesn't matter what PA9 is it can be output or Tx of Uaert1). I've checked the errata sheets. See details for more information...

I've made a software so small that it does only the following steps:1) init clock and everything to work.2) in the main program I set PIN GPIO_A_8 to input with pull up enabled, nothing is connected to that pin except for a scope probe.3) then I conf...

Resolved! __nop() taking more than one clock cycle?

I decided to run an experiment on my STM32F767ZI microcontroller. I turned on the cycle count register (DWT->CYCCNT) and decided to run the program step by step on Keil. I set the clock to the maximum amount possible with a PLL on this MCU, which is ...
